Regarding the frequent motor failure in 2XZ rotary vane vacuum pumps
Thread Content
For the 2XZ-0.5 rotary vane vacuum pump, why does the motor burn out frequently? Is there anyone who can help analyze why the motor of this type of vacuum pump keeps burning out?
Can the shaft be turned manually? Foreign objects may have entered, the vane may not be sliding smoothly, or there may be dry grinding due to a lack of oil, resulting in friction between the vane and the slide or pump walls; disassemble it for cleaning
Is it common to operate in a condition where there is direct connection to the atmosphere? If air is continuously drawn in from the atmosphere, it will also result in excessive power consumption.
